Abstract

Prediction is a means of forecasting a future value by using and analyzing historical or current data. A popular neural network
architecture used as a prediction model is the Recurrent Neural Network (RNN) because of its wide application and very high
generalization performance. This study aims to improve the RNN prediction model’s accuracy using k-means grouping and
PCA dimension reduction methods by comparing the five distance functions. Data were processed using Python software
and the results obtained from the PCA calculation yielded three new variables or principal components out of the five
examined. This study used an optimized RNN prediction model with k-means clustering by comparing the Euclidean,
Manhattan, Canberra, Average, and Chebyshev distance functions as a measure of data grouping similarity to avoid being
trapped in the local optimal solution. In addition, PCA dimension reduction was also used in facilitating multivariate data
analysis. The k-means grouping showed that the most optimal distance is the average function producing a DBI value of
0.60855 and converging at the 9th iteration. The RNN prediction model results evaluated based on the number of RMSE
errors which was 0.83, while that of MAPE was 8.62%. Therefore, it was concluded that the K-means and PCA methods
generated a more optimal prediction model for the RNN method.
